            Bug ID: 100346
           Summary: [11 regression] printf tests fail after r11-6755
           Product: gcc
           Version: 11.1.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: seurer at gcc dot gnu.org
  Target Milestone: ---

g:3804e937b0e252a7e42632fe6d9f898f1851a49c, r11-6755

There are 3 similar failures starting with this revision on a powerpc64 power 9
LE system.  I tried this on some other systems (power 7, 8, and 10) and on all
of them the tests were flagged as unsupported so perhaps that is all that is
needed here?

Clearly some that doesn't support DWARF5 properly.

It was failing with binutils 2.27 (I believe, it was the distro one) and when I
switched to binutils 2.36.1 it works.
